Planned Navy spending cuts will eliminate $219 million in shipyard work in San Diego in the middle of the year, in addition to canceling $83 million worth of aircraft maintenance here and deferring three local military construction projects.

Late Friday, the chief of naval operations, Adm. Jonathan Greenert, released a breakdown of how he will handle the Navy budget shortfall resulting from the lack of a 2013 congressional appropriations bill. His move follows increasing pushback from military leaders to lack of action from Congress.

For California, the planned cuts equal $681 million in spending this year.

The budget ax falls heavily on San Diego, home to the much of the Pacific Fleet. Ten ships based in San Diego or scheduled to visit will have maintenance delayed at local shipyards between April and September, according to information obtained from the Navy.

During the same period, regular aircraft maintenance done at North Island Naval Air Station will be curtailed to save $83 million. That kind of work is done at the station’s Fleet Readiness Center, which employs 3,700 federal workers and 500 civilian contractors.

It’s the first time the Navy has placed figures on how its belt-tightening will look in San Diego.

Mark Cafferty, president of the San Diego Regional Economic Development Corp., said the news makes previous budgetary warnings from military leaders “get real very quickly” for the region.

“These cuts threaten the foundation of our entire economy,” Cafferty said. “They will have far reaching implications beyond the defense community. Every San Diegan has a neighbor, a friend, a family member, a colleague, or an associate with ties to military spending.”

As for military readiness, Eric Wertheim, a defense analyst at the U.S. Naval Institute, said it won’t be clear what this means until the Navy says specifically which repairs or types of modernization might be delayed.

“It’s like doing maintenance on your car. Sometimes, you just don’t have the money to do the things you want to do. But we do know that delaying maintenance on ships, over the long term, affects their performance,” he said. “And you want to get the most out of these vessels.”

Wertheim added that, “It was smart that the Navy announced the delays. This is like a shot across the bow. They’re telling people that if the money isn’t there, it will have consequences.”

The other reductions will affect construction contractors.

The Navy expects to defer three military construction projects in San Diego, one in Orange County’s Seal Beach and one in Point Mugu in Ventura County to save $183 million. In addition, eight demolition projects will be canceled, including three in San Diego, all of which would have cost $13 million.

A spokesman for the Navy’s Southwest region didn’t have details Friday night on which projects are affected.

Statewide, facilities and base operations spending programs will be cut by $148 million.
